$2 {x}^{2} \: + \: 14x \: \: - 120 \: \: = \: \: 0$


​

Answer 1

Step-by-step explanation:

if we divide by 2 , then it would be $

= x² + 7x - 60

= x² + 12x - 5x - 60

= x(x+6)-5(x+6)

answer is (X+6) and (x-5)

Answer 2

$\huge\color{pink}\boxed{\colorbox{red}{❥Answer}}$

To Factorise:-

$2x {}^{2} + 14x - 120 = 0$

$2x {}^{2} + 24x - 10x - 120 = 0$

$2x(x + 12) - 10(x + 12) = 0$

$(2x - 10)(x + 12) = 0$

$x = 5 \: or \: x = - 12$
